I was trying to load a GGC with comboboxes. However, I found that I had to load the GGC before I could use it in a button callback. Otherwise, I receive a "Object reference not set to an instance of an object." error. I am not sure why I have to load the GGC in the constructor. I have included an example. Why do I have to load the GGC early?
Thanks
Ray.
